Re wiring to to 12-2 /14-2
Tomorrow i will start getting estimates for a re wire of this house that was built in the late 50's.Just wanted to get some prior knowledge and heads up from here prior to those estimates.. The wire for everything electrical in this house right now is copper that has a black and neutral wire wrapped in a almost fiberglass looking woven cloth insulation material. I guess back when this house was built a ground was not used?? The big thing is after the re wire have a ground,for some good safety and insurance reasons.
Can new wire be routed into all the existing metal receptacle and switch boxes? or do new boxes need to be cut into all the walls?
What happens to the old wire within the framed? does it just get cut and left as it seems to be stapled ,or somehow pulled out?
In a possible short interim to re wireing to get a ground at a receptacle: can the black and neutral wires be hooked up as usual,then hook up a short piece of bare copper wire from the green screw on the receptacale then attaching the other end of that bare wire to the metal box?
sorry to be so long winded..
